The random movement of molecules and ions down their concentration gradient (meaning from an area of high concentration to an area of low concentration) is called simple diffusion. Simple diffusion is related to the magnitude of driving force, permeability of the membrane, and surface area.

What is osmosis and facilitated diffusion?
Diffusion is the net movement of particles(atoms,ions or molecules) from a region where are of higher concentration to a region where they are of lower concentration, down a concentration gradient.Factors that affect the rate of diffusion1.Temperature2.the concentration gradient3.Physical movement4 surface area to volume ratioThe passage of water from the less concentrated solution to the more concentrated solution across a partially permeable membrane is a process called osmosis
Do Molecules naturally move from areas of low concentration to high concentration?
Molecules tend to move into areas where there are less molecules. This is called diffusion and can happen with or without energy.
A type of passive diffusion where water moves through a semipermeable membrane toward an area of higher solute concentration is called?
I assume you're talking about Osmosis, but I believe there are actually other similar processes as well.
What is diffusibility?
DIFFUSIBILITY The quality of being diffusible; capability of being poured or spread out.
How do air molecules attract odors?
Air molecules do not attract odors. It is a natural process called diffusion, in which particles move from an area that has a high concentration of itself to a place where there is a lower concentration of itself.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What is water uptake at the roots?
water uptake at the roots is called osmosis,this is the movement of water molecules from a region of lower concentration to a region of higher concentration against concentration gradient
What is the movement of water across a concentration gradient called?
Its called as Osmosis
What is the movement of molecules from great concentration to lesser concentration?
The movement of molecules from great concentration to lesser concentration is called diffusion. However when dealing water molecules it is referred to as osmosis.
Movement of molecules from high high to low concentration?
Movement of molecules 4m higher to lower concentration is called osmosis
What proceeds against a concentration gradient?
Molecules can move against concentration gradient by a movement called active transport. Molecules move from an area of low concentration to an area of high concentration by using chemical energy called ATP or an electrochemical gradient--either way, it uses cellular energy.
What is the difference in the concentration of a substance across a space is called concentration?
Concentration Gradient
What is A cell moving particles with the use of energy is called?
Active transport: The movement of particles against the concentration gradient into or out of a cell. Bulk transport:The movement of large molecules into or out of the cell. Both of these require energy
What does it means if a substance moves down its concentration gradient?
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
What is the process by which molecules move from high concentration region to low concentration region without the presence of membrane?
This process is called diffusion. It is the passive movement of particles from high to low concentration, and is against a concentration gradient. Hope this helps!
The difference in concentration of a substance across space is called a?
it is called a concentration gradient.
What is a differences in concentration called?
concentration gradient
